| Outline of Final Research Achievements |
We previously reported some success repairing osteochondral defects with BMSC s, but did not regenerate new hyaline cartilage with the properties of native articular cartilage. To find better methods for regenerating articular cartilage defects using BMSCs, we hypothesized that the induction of chondrogenic differentiation and the seeding of many cells into the tissue matrix within the defect are important. We determined culture conditions that created stable scaffold-free cartilage-like cell-sheets from human BMSCs and assessed their effects after transplantation into osteochondral defects in nude rats. The results indicate that the FGF-2 enhances the proliferative and chondrogenic capacity of hBMSCs during expansion. Culture with FGF-2 with FBS may help to quickly generate sufficient numbers of cells to create stable and reliable scaffold-free cartilage-like cell-sheets, which contribute to the regeneration of osteochondral defects.
